BACKGROUND Polymorphisms in dopaminergic genes may influence cigarette smoking by their potential impact on dopamine reward pathway function. A1 allele of DRD2 gene is associated with a reduced dopamine D2 receptor density, and it has been hypothesised that A1 carriers are more vulnerable to smoking. In turn, the 9-repeat allele of dopamine transporter gene(More)
Insect venom allergy (IVA) may result in the most severe systemic reactions seen in allergology. The only potentially curative treatment option is venom immunotherapy (VIT) over 3 to 5 years. This treatment is effective in more than 90% of subjects but no reliable predictors of VIT effectiveness exist. Sting challenge with a living insect can be performed(More)
OBJECTIVE To present current guidelines regarding treatment of mastocytosis in pregnancy on the example of observed patients. DESIGN Case control national study. SETTING Polish Center of the European Competence Network on Mastocytosis (ECNM). POPULATION OR SAMPLE 23 singleton spontaneous pregnancies in 17 women diagnosed with mastocytosis in years(More)
Mastocytosis is an uncommon disease classified as a myeloproliferative neoplasm, however, its symptoms are broad and place patients at crossroads between dermatology, hematology and allergology. Patients with mastocytosis often suffer from symptoms resulting from the activation and release of mediators from the mast cells, such as generalized itching,(More)
Mastocytosis is a rare disease characterized by activating KIT mutations and clonal expansion of mast cells (MCs) in tissues, particularly in skin and bone marrow. Symptoms of mastocytosis always correlate with the extent of MC infiltration and include urticaria pigmentosa, anaphylaxis, flushing, headache, diarrhea, osteoporosis and pruritus. Interleukin 31(More)
Obesity and asthma are both important public health issues. Increasing number of studies suggest the association between obesity and asthma which may be causal or accidental. The studies on animal models show innate enhancement of airway hyper-responsiveness which suggest that chronic airway hyper-responsiveness may be related to chronic low-grade systemic(More)
